[[Value over replacement player]] (VORP) {{clarification needed span|text=was once considered a popular sabermetric statistic.|reason=What became of it, and why - with appropriate citation(s), please.|date=July 2024}} This statistic attempts to demonstrate how much a player contributes to his team in comparison to a hypothetical player performing at the minimum level needed to hold a roster position on a major league team. It was invented by Keith Woolner, a former writer for the sabermetric group/website ''Baseball Prospectus''.

[[Wins above replacement]] (WAR) is another popular sabermetric statistic for evaluating a player's contributions to his team. Similar to VORP, WAR compares a given player to a replacement-level player in order to determine the number of additional wins the player provides to his team relative to an average ballplayer at his position.<ref name=":7">{{Cite web|url=http://www.espn.com/blog/sweetspot/post/_/id/27050/what-we-talk-about-when-we-talk-about-war|title=What we talk about when we talk about WAR|last=Schoenfield|first=David|date=July 19, 2012|website=ESPN.com}}</ref> WAR, like VORP a ''cumulative'' statistic, heavily reflects the amount of a player's playing time.<ref name=":7" />

"Static" statistics based on simple ratios of already accumulated data (like batting average) and accumulative tallies (such as pitching wins) do not fully reveal all aspects of the game represented in their numeric totals.<ref name=":8">{{Cite book|last1=John T.
